Most sequence generators yield a PRBS (pseudorandom bit sequence) from a shift register with appropriate feedback. Thus, the sequence has limited length, and the generator continuously repeats the ...

This principle would not create a good random number sequence if used alone, but it can not cause the TRNG performance degradation, as the entropy can only grow.

Instead, random-number generators that are often used to produce such sequences tend to cluster zeros together, introducing a bias.

It’s a ridiculously easy sequence to make, and yet it fooled programs designed to root out underlying order in seemingly random numbers. David Gawen Champernowne was born in 1912.

Cryptography systems tend to rely on “pseudo random-number” generators that output sequences of numbers that are nearly random. While some of these generators are very good, a cryptography system ...

To foil would-be hackers, computer systems need to generate sequences of random numbers. Some systems use what’s known as pseudo-random numbers, which are actually complex patterns that begin with a ...

You-Qi and co say their random number sequences pass all these tests with flying colors. The end result is the fastest quantum random number generator ever produced by some margin.

Researchers have built the fastest random-number generator ever made, using a simple laser. It exploits fluctuations in the intensity of light to generate randomness—a coveted resource in ...
